Given numbers are 485, 705, 840, 971
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(485, 705) = 68385
GCD(485, 705) = ( 485 x 705 ) / 68385
= 485 / 705
= 485
Step2:
LCM(5, 840) = 840
GCD(5, 840) = ( 5 x 840 ) / 840
= 5 / 840
= 5
Step3:
LCM(5, 971) = 4855
GCD(5, 971) = ( 5 x 971 ) / 4855
= 5 / 971
= 5
So, Greatest Common Divisor of 485, 705, 840, 971 is 1
